CAUTION: Always install end-play adjustment
shims on the magneto side between bearing
and crankshaft counterweight.
The following is required for the adjustment pro-
cedure:
– adjustment shims (refer to Parts Catalog)
THICKNESSES AVAILABLE
0.10 mm (.004 in)
0.20 mm (.008 in)
0.30 mm (.012 in)
0.50 mm (.020 in)
– micrometer
– caliper.
Total shim thickness needed for the end-play ad-
justment is determined with the following proce-
dure:
• Measure crankcase halves as illustrated (M
1
and M
2
).
A standard compressed crankcase gasket will
have a 0.30 mm (.012 in) thickness (M
3
). Add
these measurements to obtain dimension A.
